TIRE-HEATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 692,376, dated February 4, 1902.

Application filed September 277, 1901. Serial No. 76,747. (No model.)

To @ZZ whom, it may concern:

Be it known that I, CHRISTOPHER SoLBERG, a citizen of the United States, residing at Eden Valley, in the county of Meeker and State of Minnesota,have invented certain newand useful Improvements in Tire-Heating Devices; and I do hereby declare the following to be a full, clear, and exact description of the invenlion, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved tire-heating device adapted for easy adjustment to tires of different sizes;

and to this end it consists of the novel de-V vices and combinations of devices hereinafter described, and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout both views.

Figure 1 is a view in central vertical section showing a tire-heating device constructed in accordance with my invention, and Fig. 2 is a plan view of the said device with parts broken away and with others removed.

The numeral 1 indicates a hollow body, which preferably contains asbestos wool or other absorbent non-combustible material 2. This member 1 affordsa generating-chamber and, as shown, is supported at a suitable distance above the ground or floor by legs 3. A hollowT tubular standard 4, which is screwthreaded on its exterior, rises from the top of the member 1 and communicates therewith at its lower end through a small passage which is adapted to be opened and closed by a needle-valve An oil-tank 6 is secured to the Lipper end of the hollow support 5 and communicates therewith. To protect this tank 6 from intense heat, it is shown as provided with au outwardly-spaced asbestoslined jacket 7. At its upper end the stem of the needle-valve 5 is shown as provided with a hand-wheel 8 and has screw-threaded engagement with a hub 9, secured on the top of the said tank. This screw-threaded engagement serves to hold the valve 5 in any set position.

The numeral 10 indicates an ordinary burner, such as used in gasolene stoves, which burner is located immediately below `twyersupporting prongs 14.

the generating-chamber 1 and communicates therewith through a small pipe 1l.

To the peripheral portion of the chamber or member 1 is secured a plurality of hinged lugs 12, and to. each of these lugs is pivoted the lower end of a tire-supporting arm 13, which is bifurcated at its upper end to afford The upper portions of these prongs 14 are provided with tire-holding notches 15, and the sides thereof are provided withlongitudinally-extended slots 16.

A disk-like nut 17, provided with handpieces 18, works with screw-threaded engagement on the tubular support 4. A non-rotary ring 19 is moved vertically by the said nut 17, the same having Vflanges which loosely embrace the said nut. Links 20 connect the non-rotary ring 19 with the intermediate porlions of the several supporting-arms 13. As is evident, by turning the nut 17 the ring 14 may be moved upward or downward, so as to adjust the free ends of the arms 13 toward or from the central supporting-tube 4, keeping the same always in circular line concentric with the said support 4.

For each supporting-arm 13 there is a twyer or burner 2l, which, as shown, is afforded by a hollow head having one or more jets or perforatious 22 and also a pair of trunnions 23, which work one in each of the slots 16 ofthe embracing-prongs 1-1 of the corresponding arms 13. Each twyer 2l is connected by a small pipe or tube 24 with a radially-projecting tube 25, which, as shown, opensdirectly from a gas-outlet sleeve 2b', which sleeves 2G open radially from the generating-chamber 21. The pivotal connections 27 between the tubes 24 and 25 are afforded by suitable flexible and hollow joints-such, for instance, as used in adjustable gas-fixtures. The inner ends of the gas-outlet sleeves 26 are adapted to be simultaneously opened and closed by a perforated ring or annular valve 28, Vwhich is suitably mounted within the generatingchamber and is provided withinternal gearteeth 29. The teeth 29 are in mesh with the teeth of a small segmental gear 30, carried at the lower end ofa short vertical stem 3l,whicl1 is suitably mounted in the upper wall of the chamber or member 1 and is provided witha handpiece 32, by means of which said stem may be turned and said valve 28 adjusted.

33 indicates a tire, such as a wagon-tire, shown as supported by the several arms 13. The manner in which the several radial tire-supporting levers 13 are adjusted vis obvious and has'already been stated. The adjustments of the said supporting-levers, as is further evident, cause corresponding adjustments ofthe several twyers or gas-burners 2l, so that the latter are always kept in position to properly apply the iiame to the tire. When the said levers 13 and twyers are adjusted, the trunnions 23 move in the slots 16 to prevent binding of the parts. f

The device above described is extremely eflicient for the purposes had in View. It may be made in various sizes and may be designed so that it is adaptedy for heavy work, such as heating the tires ot' locomotive drivewheels. The device is always ready for use, and only such an amount of fuel will be used as is absolutely necessary'in order to produce s`uicient heat to expand the tire to the desired extent.

The device illustrated in the accom panying drawings is of course capable of considerable modification within the scope of my invention as described.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

l. In a tire-heating device, the combination with a common support, cfa plurality of radially-adjustable burners, and a plurality of radially-adj ustabletire-supports,w ich burners and supports are movable toward and from the axis of said commonlsupport.

2. In a tire-heating device the combination with a plurality of tire-supports and burners` arranged in concentric circles, of means for supplying the combustible fluid to said burners, and means for imparting common raiial adjustment to said supports and burners toward and from the axis of said common support, substantially as described.

3. Inatire-heating device, the combination with a centrally-located support, ot a plurality of tire-supporting arms pivoted to said sup.- port at their lower ends and adjustable radially toward and from the axis thereof, of a vertically-adjustable element at the axis of said series of supporting-arms, links connecting said adjustable element with said supporting-arms, for imparting common adjustments thereto, and means for applying heat to the tire, substantially as described.
